  • New Linux System Call Proposed To Let User-Space Pin Themselves To Specific CPU Cores

    A "pin_on_cpu" system call has been proposed for the Linux kernel as a new means of letting user-space threads pin themselves to specific CPU cores. User-space processes requesting to be run on specific CPU cores can already e done by the likes of Linux's sched_setaffinity to get/set the CPU affinity mask while pin_on_cpu would be a new and simpler way.

  • First ‘ktown’ Plasma5 update for Slackware in 2020

    Slackware and Plasma5… what will 2020 bring? For starters, Pat just added Kerberos to Slackware-current! That is the first (small but significant) step towards a big change in Slackware which will unfold over the coming period. And at the end of that, I expect that Plasma5 gets folded into the distro as well. Here’s hoping! In any case, I just released KDE-5_20.01 and the packages are available for download from my ‘ktown‘ repository. As always, these packages are meant to be installed on a full installation of Slackware-current which has had its KDE4 removed first. These packages will not work on Slackware 14.2.

  • An Open Source Effort to Encrypt the Internet of Things

    End-to-end encryption is a staple of secure messaging apps like WhatsApp and Signal. It ensures that no one—even the app developer—can access your data as it traverses the web. But what if you could bring some version of that protection to increasingly ubiquitous—and notoriously insecure—internet-of-things devices?

  • Why UK leaders need open technology for the disrupted future

    We’re not quite past the post with Brexit, but thankfully, we have moved beyond the Brexit hiatus. And, it’s time we did. Whatever your views on the merits of Brexit, as the UK’s Prime Minister has stressed, it’s time to move on and move forward. In fact, there may be no better time to spread the word about being open for business by highlighting the benefits of open technology. It is a task that all business leaders in the UK need to embrace. By seizing the moment to “get open done”, we can not only develop and sustain the UK’s leadership in open technology, but also carve out our status on the world stage for many years to come. The timing couldn’t be better. It’s a pivotal moment to demonstrate how declaring our independence of European markets does not equate with a lack of collaboration or creativity. Brexit offers us a convenient pause; a time for us to take stock and reflect on who we are as a nation and what we can offer global markets. We’ve had our fair share of inventors and game-changers in the past. Now, we have an opportunity to show the UK can lead in technology.

  • Acculturation Guide

    The Acculturation Guide is a hands-on “boot camp” for those interested in the configuration, administration and operation of applications on YottaDB. This file is the script (or workbook) for the workshop, consisting of the exercises below.

    At the end of these exercises, you should have a basic working knowledge of the essential aspects of YottaDB Administration and Operation. While this workshop alone will not by any means make you a YottaDB expert, the basic working knowledge it will give you will help you to quickly understand the concepts explained in the user documentation and put you on the path to becoming an expert.

    The workshop is not a course in programming with YottaDB. Familiarity with Linux® (or at least UNIX®) will allow you to move faster through the material, but is not absolutely required. If you have no experience whatsoever with Linux or UNIX, supplementary tutorial material on the side will increase your level of comfort.

  • Where InfluxDB time series database is going

    Paul Dix: So in mid-2012, I started this company and basically we wanted to build a SaaS [software as a service] product for doing real-time metrics and monitoring. Initially my idea was I wanted to do anomaly detection and machine learning on data sets, but to build that we first had to build all the infrastructure, so we could collect time series data at scale and query it. Fast forward, basically another year, and we went to Y Combinator, we did the winter of 2013 batch and this product wasn't really taking off. But I could see that there was something from an infrastructure perspective. We did have some customers paying us and I talked to them, asked why they were paying us. They told us that they were using our product as a time series platform. So we pivoted and the goal was initially to build a database, but that later morphed into being an entire platform for working with time series data. My goal was to build something that was generally useful for developers to create their applications with.

  • Accessibility checker and support for PDF/UA specs

    PDF/UA or ISO 14289 is a specifications that defines the requirements for accessibility in a PDF document. The specification defines the required structure and formatting of the document (also refers to WCAG specification from W3C for use on the web) and PDF features, which should be enabled or disabled so the document is better suited for accessibility (for example PDF tags are required). Thanks to the Dutch Standardisation Forum for financially sponsoring and Collabora Productivity in cooperation with Nou&Off for the work on implementing this specification into LibreOffice.

  • Microsoft is testing ads in WordPad in Windows 10

    Over the years Microsoft has taken numerous controversial decisions with Windows 10, including installing sponsored apps, using the Start menu to advertise apps it thinks you might be interested in, and -- of course -- the various forms of data-collecting telemetry. Now it has been discovered that more ads could be on their way. A Windows researcher has uncovered ads in WordPad encouraging people to try out Word, Excel and PowerPoint online.

  • Operator pattern: REST API for Kubernetes and Red Hat OpenShift

    In this article, we will see a similar pattern when writing the REST API in any known framework vs. writing an Operator using Kubernetes’ client libraries. The idea behind this article is not to explain how to write a REST API, but instead to explain the internals of Kubernetes by working with an analogy.

  • Rust framework dev says ‘I’m done with Open Source’…has second thoughts

    The main developer behind a Rust actor framework pulled the code behind the project in apparent protest against an “unsafe sh*tstorm” against him last week. And while the coder in question now appears to have nominated new leadership to continue the project, the apparent “ragequit” has prompted questions about the dynamics within the open source community. [...] “You could notice after each unsafe shitstorm, I started to spend less and less time with the community,” he continued. “You felt betrayed after you put so much effort and then to hear all this sh*t comments, even if you understand that that is usual internet behavior. Anyway, removing issue was a stupid idea. But I was pissed off with last two personal comments, especially while sitting and thinking how to solve the problem. I am sorry for doing that.” [SIC]

  • A quick-and-dirty guide on how to install packages for Python

    When people start learning Python, they often will come across a package they want to try and it will usually start with "just pip install it!" The problem with that advice is it's a very simplistic view of how to manage packages and can actually lead to problems down the road. And while there is a tutorial on installing packages at packaging.python.org, it might be a bit intimidating for some if they are just looking to quickly get up and going. If you just want to start poking at Python and want to avoid the pitfalls to installing packages globally, it only takes 3 steps to do the right thing.

It is an open source project released under GPLv3 and is written in Racket programming language. In this brief guide, I am going to show you how to install and play Terminal Phase space shooter game in Terminal on Linux.

Vicious Sisters follows a new protagonist, Mina Park and her first experience in the Shadow Realm. However, if you've played the previous game you might spot some familiar faces.
